Python help thread?

Start with -1, not with 0

Code:

word = 'crap'
for index in range(-1, -len(word)-1, -1):
    print(word[index]),

That works to make it horizontal, which is the biggest problem, but I'm still getting that pesky double front letter and the traceback.

Code:

Word: How in the world?
? d l r o w   e h t   n i   w o H H

Traceback (most recent call last):
  File "G:\python\backwards.py", line 11, in <module>
    backwards_word(words)
  File "G:\python\backwards.py", line 5, in backwards_word
    letter = words[index]
IndexError: string index out of range
